摘　　要：本文在分析不同类型地面运动引起抗震结构不同类型破坏的基础上,指出结构滞回耗能总量是累积破坏的重要参数,以1735条实际地震记录作为输入计算了不同动力参数单自由度体系弹性及弹塑性总输入能量及滞回耗能量,得出计算弹塑性体系滞回耗能谱的简化公式。This paper point out the hysteretic energy is key factor of the cumulative failure, based on the analysis of the failure types of seismic structures undergoing various types of earthquakes. The input energy and hysteretic energy of SDOM systems with different dynamic parameters by using 1735 earthquake records as input have been compulted, and the simplified formulas of calculating hysteretic energy is presented.

关 键 词：滞回耗能谱 抗震结构 弹塑性体系 单自由度体系 动力参数
